Thank you very much bro so I should now used
is.path.cv2.imread()?

I'm not really sure what you mean,but anyways ,you can also try putting that particular part of the code in a try except block in case you have faulty images in your directory.

Hello guys, I want to start sql but I would prefer to learn offline (ie getting data from my local pc). I don't know how to get about it. Have searched Google , I keep getting more confused. Please I need help.

Mrves111:
I want to perform multiple image processing using opencv in jupyter notebook. I tried to upload the datasets (images) that's stored in my desktop using this code:

import os
import numpy as np
import cv2

img = cv2.imread('/User/victor/Desktop/data/mask/facemask.jpg', 0)
img



import os
import numpy as np
import cv2

resize_width = 100
resize_height = 100
path = '/User/victor/Desktop/data/mask/facemask
images = [] # List to append the images as 2D numpy arrays.
target = [] # List to append the target
originalrepo = [] # Create a repo for flattened pixels

for root, dirs, files in os.walk(path):
for file in files:
with open(os.path.join(root, file), "r" as auto:
img = cv2.imread(root+'/'+file, 0)
img = cv2.resize(img, (resize_width, resize_height))
images.append(img)
# Append the flattened image to the pixel repo
originalrepo.append(img.flatten())
# Append the folder where the image is to the target list
target.append(root.replace(path,'').replace('/',''))
# Convert the repo list into numpy array
originalrepo = np.array(originalrepo)
print(originalrepo)
print(target)

I got this error :"opencv(4.5.1)/private/var/folders/nz/vv4_9tw56nv9kvyaszvwg80000gn/T/pip-req-build-39p1qqfs/opencv/modules/imgproc/src/resize.cpp:4051: error: (-215:Assertion failed) !seize. Empty() in function 'resize'

Please I'm appealing for assistance, if there's another simpler code I could use or if I made any error.
Note that I opened the jupyter notebook in the same folder that the dataset are located.

Please always use the code formatting tool to make your codes easier to read. That being said, I'm not really sure what you are trying to do but I believe you could use the Pillow library to do the same.

In what sense? What type of data are u talking about?. Do you mean offline videos, books or what?.

elvisgaga:
am sorry if my explanation is not clear enough, the thing is the online tutorial requires me to input the sql code direct in thier platform online but I would like to run the code offline but I don't know if am to use notepad, I researched it, I was seeing setting up local server but I still want the gurus here to break it down for me. Thanks

I would like to appreciate all contributors of this thread especially the op reason is this post revamped my 20 years dream of programming left incomplete, it better late than never. this is my 3rd months on SQL but am having some challenge on my script I tried using 2 fk on this table below. pls problem shared is a problem halved
created table supplier (
supplier_id number (7)not null,
supplier_name varchar2(20)not null,
country varchar2(20),
phone number (30)not null,
dates date,
orders_id number (7)not null,
qty number (7)not null,
amounts number (10,2),
shipping_id number (7)not null,
shipping_name varchar2(30),
constraint supplier_pk primary key(supplier_id),
constraint orders_pk foreign key(orders_id),
constraint shipping_pk foreign key (shipping_id),
reference orders(orders_id),
reference shipping(shipping_id));
error report missing keyword
pls urgent attention

Marveaux:
Shouldn't that be "references" not "reference"?

It's unclear, you're missing a keyword according to the error, although I can't tell which one. Can you take a better picture?

you never know when excel will come handy on the job.

very powerful if you can get the advanced concept for analytics.

DAX, power query, power pivot, pivot table and cool visualization will do fine.

Pls which version of the Microsoft Office has this features or is it only on office 365

They are all in the excel 2016, you can download the excel power query add-in if you use lower version.

Hello gurus, I,ve finally started sql, I tried using sql server with ssms but I had problem with installation which I will workout later so I opted for sqlite and db browser for now. My challenge now is do I write the query with the db browser or the sqlite itsself or better still how do work with the db browser and sqlite together ie connecting db browser with sqlite. have searched Google but the result am seeing is it's either they concentrate on db browser or sqlite. I just want to know how to connect the two together. please gurus help me solve this dilemma. thanks
